HEAD World Cup Rebels i.SL RP Ski Specs

Intelligence

HEAD'S THEORY OF RELATIVITY

Ski performance is not an absolute measure. What you want out of a ski always depends on how and where you ride.

On hard-packed slopes you want perfect edge grip. On soft snow, you want more maneuverability. Breaking the slope record you want your ski to perform differently than when you're just cruising with your friends or family.

HOW IT WORKS

Intellifibers positioned at 45° in front of the binding transform mechanical impulses into electrical energy. The harder you ride, the more energy is produced.

The electrical energy is led back to the Intellifibers. This causes them to stiffen up, putting more rebound and torsional stiffness into the ski.

WHAT IT DOES

Their 45° position in front of the binding increases the ski's torsional stiffness, pushing the edge into the snow in hard turns.

Intelligence progressively stabilizes the entire ski at high speeds.

INTELLIGENCE CHIP TECHNOLOGY - THE EXTRA BOOST

Some HEAD high-end skis boast Intelligence Chip Technology. Here, the electrical energy produced by the Intellifibers is not just recycled, but accumulated and released bit by bit through a pre-programmed chip - individually timed to match the oscillation properties of the ski.

Thus, the effect of Intelligence is multiplied, providing even more performance relative to your skiing style.

KERS

THE EXTRA BOOST

KERS Technology works like a turbo charger that provides additional power and acceleration by stiffening the tail of the ski in outturns.

The effect: a boost, catapulting the rider into the next turn. Just like when Formula 1 pilots push a button for that extra notch of speed.

HEAD KERS Technology is an electronic, fully automatic and integrated system.

HOW IT WORKS

Skis experience maximum flex at the end of a turn. At this moment the energy is released into the fibers of the tail. The tail of the ski then stiffens up, immediately increasing rebound for maximum acceleration at the end of the outturn.

TECHNICAL BACKGROUND

HEAD KERS Technology is an evolution of the idea behind HEAD's Intelligence Technology. In addition KERS does not influence the torsional stiffness of the ski, KERS empowers the skis longitudinal flex. Also KERS Technology is based on a completely new design capable of accumulating power and keeping it in store for the right moment.

Piezoelectric fibers transform kinetic energy into electrical energy which is stored. Electrical energy is immediately released to areas of the ski, where additional energy is requested. Timing and release are automatically controlled and coordinated. Depending on the flex pattern of different ski models, sensors are programmed beforehand: the more aggressive the ski has to be, the stiffer the tail will become.
